           "<resources>");
   
   apkAnalyzer.resNames("string", "default", null)
           .doOnNext(s -> stream.print("<string name=\"" + s + "\">"))
           .flatMap(key -> apkAnalyzer.resValue("string", "default", key, null))
           .doOnComplete(() -> {
               stream.print("</resources>");
               apkAnalyzer.close();
           })
           .subscribe(value -> {
               stream.print(value);
               stream.print("</string>\n");
           });

   ApkAnalyzer apkAnalyzer = new ApkAnalyzer(apkPath);
   
   String packageName = apkAnalyzer.manifestAppId();
   Disposable disposable = apkAnalyzer.resNames("string", "default", null)
           .doOnNext(s -> stream.print(packageName + ":string/" + s + " = "))
           .flatMap(key -> apkAnalyzer.resId("string", "default", key, null))
           .doOnComplete(apkAnalyzer::close)
           .subscribe(s -> stream.print(s + "\n"));
   
   stream.close();
